Answer:
x = 8
Explanation:
Given :
To find :
the value of x
Solution :
The relation between coefficient of cubical expansion and coefficient of linear expansion is given as,
γ = 3α
where
γ denotes the coefficient of cubical expansion
α denotes the coefficient of linear expansion
As given,
γ₁ : γ₂ = 2 : 3
Then, the ratio of the coefficients of linear expansion is
α₁ : α₂ = γ₁/3 : γ₂/3
= γ₁ : γ₂
= 2 : 3
The linear expansion is given by,
∆l = lα∆T
l denotes the initial length
∆T denotes the change in temperature
Let l₁ and l₂ be the lengths of the two rods.
l₁ : l₂ = 4 : 3
The value of x is 8
